SPRAY DEVICE Filed March 6. 1929 2 Sheets-Shee 2 lnvegor 0320.5.JQ22619By @mwfih A ttorney Patented July 7, 1931 PATENT OFFICE OTTO L. JANSKY,OF PITTSBURGH, PENNSYLVANIA SPRAY DEVICE Application filed March 6,1929. Serial No. 344,842.

This invention relates to an improved spray device which is especially,but not necessarily, adapted for spraying paint and analogous liquids,and it has more particular reference to a structure which embodies apressure supply head and compressed air conducting hose, an air inletpipe, a fluid out let pipe and an eduction pipe, these being associatedwith a novel supporting device n for the paint container.

In carrying out the improved invention, I have evolved and produced anovel assembly constituting an adjustable support for the liquidcontainer to be dispensed and this embodies a jar-like casing for thepipe constructed with the removable top carrying the pipe assembly. Apredominating feature in the construction is found in the utilization ofstandardized attachments constituting covers for the paint cans, thesecovers being associated with the casing and detachably connectedthereto,

whereby to accommodate cans of varying diameters. Other specificstructural features of the invention will become more readily apparentfrom the following description and drawings.

In the drawings: Figure 1 is an elevational view of the sup- 39 portingbracket and the pipe casing with the cap structure and piping assemblyremoved. Figure 2 is a sectional and elevational view of-the completestructural organization con-- V an air passage which communicates withthe stituting the working dispenser.

tional views taken on the planes of the horizontal lines 33 and 4-4respectively of Figure 2.

Figure 5 is a perspective view of a supporting bracket.

The entire structure may well be seen in Figure 2, wherein it will beobserved that the reference character 6 designates an L-shapedsupporting bracket. The vertical leg or arm 7 of this is formed with aplurality of aper tures. The horizontal arm 8 is provided with anadjustable set screw 9 having an appropriate operating knob and swivelhead for engaging the removable paint can 10.

5c The paint can is a stock part and constitutes Figures 3 and 4 aretransverse cross sec-- no portion of this invention. The importantfeature to be noted in connection with this paint can is the disc-likecover plate 11, therefor. This comprises a metal disc having openingsformed in the center for passage of 1 pipes to be hereinafter describedand it is formed with the thickened marginal depending flange 12.

In practice, various cover plates will be provided, in order toaccommodate cans of difierent diameters. In each instance, however, theexternal diameter of the flange 12 will be standardized to adapt it foruse in connection with the other parts of the structure.

Associated with the cover plate 11 is a jar-like casing 13 ofappropriate material. This is provided at its bottom with an outwardlyoffset annular flange 14 which embraces and is fastened to the flange 12by way of retaining screws 15. Formed integrally with the flange 14 is aguide 16 in which is slidably mounted the upstanding arm 7 of thebracket 6. The casing 13 has a reduced screw threaded neck 17 on which ascrew-threaded cap is removably fitted. This cap carries the pipeassembly. For in- I stance there is an attaching arm 19 having acircular flange 19 depending from its free end portion in which isinserted-the upper end of a tubular handle 20 to the lower end of whichis coupled the air supply hose 21.

The handle 20 is, of course, provided with air hose 21 and said handleis detachably clamped in the flange 19 by a set screw 20. A valve A isprovided for controlling. the

passage of the air'through the handle.

In addition there is an air inlet pipe'22 of general U-shaped designhaving a long branch depending through the casing. 13 and extendingdownwardly through an opening in the cover plate 11 into the interior ofthe paint can 10. Associated with this is an eduction pipe 23 having itsdischarge end portion seated in a notch in a bracket 24, carried bytheattaching arm 19. The other end of the pipe 23 communicates with the airpassagein the handle 20. The reference numeral 25 designates a fluidoutletpipe: r

t clamping said can in the cover which extends down through the arm 19through an opening in the cap 18 and through an opening in the coverplate 11 into the interior of the paint can 10 where it terminates inspaced relation above the bottom thereof.

The entire arrangement is assembled as seen inFigure 2. The member 13 isthreaded into the cap 18 and the cover plate 11 is secured by set screws15 in the flange 12 with the pipes 22 and 25 extending-therethrough. Thepipe 22 is sufficiently flexible to permit the free end thereof to beinsertedin the opening provided therefor in. the cover plate 11 whensaid cover plate is being positioned. The bracket 6 is adjusted on themember 13 as desired, andthe can 10 is then inserted 'inthe cover plate11. Then, the screw 9 is engaged with the bottom of the can for plateand the device is ready for use.

The invention is noted for its compactness and convenience inarrangement of parts and the economical construction and relative asociation thereof. It is regarded as a practical contribution to theart, is capable of 'fulfilling the requirements of an invention ofthis'class in a more satisfactory manner and 'is otherwisedistinguishably different from outlet pipe extending downwardly throughthe cap and an air eduction tube operatively associated withthe fluidoutlet pipe for elevating the fluid from the receptacle, comprisprisinga substantially cylindrical member detachably connected to the cap,saidmem- 'berbeing open at its ends, a cover plate detachably securedtothe lower end portion of the memberhaving an opening-therein for thepassage ofthe fluid outlet pipe, a mar-- ginal flange depending fromthecover plate for the reception of the receptacle, and means mounted onthe member and engageable with the receptacle for removably clampingsaid receptacle against the cover plate.

2. Means for operatively mounting a fluid containing receptacle on apneumatic spraying unit otthe'typehaving a screw cap and a fluid outletpipe extending downwardly through the cap and an air eduction tubeoperati'velyg asso'oiated with the fluid outlet pipe for elevating thefluid from the receptacle, comprising a substantially cylindrical memberhaving a threaded neck for threaded engagement with the cap fordetachably mounting the member thereon, said member being open at itsends, an outwardly offset flange on the lower end of the member, a coverplate disposed within the flange and including a depending marginalflange, means for detachably securing the coverplate in position, saidcover plate having an opening therein for the passage of the fluidoutlet pipe, said cover plate adapted for the reception of thereceptacle, and meansfor removably securing the receptacle in operativeengagement with the cover plate.

3. Means for operatively mounting a fluid containing receptacle onpneumatic spraying unit of the type having a screw cap and a fluidoutlet pipe extending downwardly through the cap and an air eductionpipe operatively associated with the fluid outlet pipe for elevating thefluid from the receptacle comprising a. substantially cylindrical memberhaving a threaded neck for threaded engagement with the cap fordetachably mounting the member thereon, said member being open at itsends, an outwardly ofiset flange on the lower end of the member, a coverplate disposed within the flange and including a depending marginalflange, means for detachably securing the cover plate in position, saidcover plate having an opening therein for the passage of the fluidoutlet pipe, said cover plate adapted for the reception of thereceptacle, and means for removably securing the receptacle in operativeengagement with the cover plate, the last named means including anangular bracket slidably adjustable on the first named flange and havingone end disposed beneath the receptacle, means for securing the bracketin adjusted position, and a screw threadedly mounted on said one endportion of the bracket and engageable with the receptacle for clampingsame against the cover plate within the second named flange.

In testimony whereof I afix my signature.
